ABSTRACT:
Composite powder metal parts made of separate and distinct powders are produced by forming a low density preform of a first powder and then using the preform to define a part of the cavity employed to accommodate the second powder prior to final compaction. The cavity employed in forming the preform is defined by a die wall and a major diameter of a trailing section of a concentrically disposed core pin. A second cavity for the second powder is formed between the preform and the minor diameter of the distal section of the core pin.
